6-Point Impact Sockets

Achieve the best possible grip on hex fasteners and prevent rounding. These sockets are made to withstand the high torque and force of impact tools.

3/4", 1", and 1 1/2" square drive size sockets require a locking retainer. Use with an impact wrench that has a pin-style socket retainer, or use a socket retaining ring with tools that have a hole- or hole-and-ring style socket retainer.

Wheel Bearing Locknut Socket Sets


Display Rack	6-Point
	6-Point Rounded
	8-Point

Shaped and sized for compatibility with wheel bearing locknuts on trucks and trailers, the sockets in these sets make it easy to install and remove locknuts. They ensure the proper torque setting when you reinstall a locknut on your wheel, so you know it's safe and secure. These are square drive sockets for use with hand-driven tools, not impact wrenches. Made of steel, they grip locknuts tightly and prevent rounding.

6-point sockets are designed for use with hex locknuts.

6-point rounded sockets fit the special rounded hex nuts found on some trucks.

8-point sockets fit 8-point nuts and square nuts.

Choose sets with a display rack to keep sockets contained and organized in a single location. The display rack mounts to walls and is labeled by socket size.
